Kuhnke

Your Trusted Source for Kuhnke Automation: A Decade of Industrial Expertise

While Kuhnke has a profound engineering legacy renowned for mastering pneumatic technology, precision solenoids, and industrial electronics, Atlantech Drives & Controls brings a modern, agile approach to sourcing these critical components.

Founded in 2017, Atlantech Drives has spent a decade building a robust global supply chain dedicated to industrial automation. We understand that Kuhnke products—from their legendary miniature pneumatics to their seamless integration as an official distribution partner for Hengstler—are the lifeblood of countless manufacturing plants, medical devices, and railway systems worldwide.

Whether you need a modern CODESYS programmable controller or a desperately hard-to-find legacy component, Atlantech Drives is your definitive procurement partner.

Comprehensive Kuhnke & Hengstler Product Portfolio

Kuhnke’s product range is characterized by its extraordinary breadth, flawlessly bridging the gap between fluid power and electronic control. At Atlantech Drives, we supply their complete catalog:

1. Advanced Pneumatic Technology

Kuhnke originally built its global reputation on miniature pneumatics and has since expanded to engineer solutions for all industrial requirements.

  • Valves and Actuators: A comprehensive range of directional control valves (NPT and BSP up to 1/2″) and rugged pneumatic cylinders (up to 125 mm bore).
  • Integrated Solutions (Electro-Pneumatics): Specialized devices like the Airbox and Kuhnke Smart cylinders that seamlessly merge electronic commands with pneumatic actuation.
  • Logic and Accessories: Pneumatic timers, precise pressure regulators, and mechanical counters for non-electrical logic circuits.

2. Industrial Solenoids & Electromechanical Actuators

Manufacturing solenoids is a core technology for Kuhnke, resulting in one of the widest and most reliable ranges available globally.

  • Linear & Rotary Solenoids: High-speed, high-force actuators perfect for sorting mechanisms, packaging lines, and locking devices.
  • Bistable & Heavy-Duty Types: Energy-efficient bistable solenoids that maintain their position without continuous power, ideal for battery-operated or heat-sensitive environments.

3. Electronics, IPCs, and CODESYS Control

Since 1977, Kuhnke has been at the forefront of Programmable Logic Controllers (PLCs) and industrial computing.

  • Controllers: Modern PLC and Interprocess (IPC) solutions fully programmable with standard CODESYS software.
  • Connectivity: Systems natively designed to support all major fieldbus communication interfaces, including CANopen, PROFIBUS, and EtherCAT.

4. Hengstler Encoders & Feedback Systems

Through its highly successful official partnership, Kuhnke serves as a primary distributor for Hengstler, allowing us to supply world-class rotary feedback systems:

  • Incremental & Absolute Encoders: Available in solid shaft and hollow shaft configurations, offering single and multi-turn absolute precision up to 29-bit resolution.
  • Specialized Environments: ATEX-certified explosion-proof encoders, heavy-duty stainless steel models, and extreme high-temperature variants.

The Ultimate Solution for Obsolete Kuhnke Relays

One of the biggest challenges in industrial maintenance today is sourcing replacement relays. Kuhnke’s relay division, established in 1948, became an industry standard in power generation, railway, and medical sectors.

However, because the relay division was sold in 2004, thousands of these critical components were rebranded, discontinued, or phased out. Do not upgrade your entire electrical cabinet just because a single legacy relay failed. Atlantech Drives specializes in locating these obsolete and hard-to-find Kuhnke relays.

Our dedicated procurement team leverages a decade of global networking to find the exact vintage New Old Stock (NOS) or refurbished component you need to get your machine running today.

Troubleshooting Kuhnke Pneumatics & Electronic Faults

Rapid diagnostics save money. If your Kuhnke pneumatic valve fails to actuate, always check the solenoid coil first; voltage spikes often cause the coil to burn out before the mechanical valve spool fails, meaning you only need to order a replacement coil.

For Kuhnke CODESYS PLCs experiencing a sudden «Bus Fault» (indicated by a flashing red LED on the communication module), verify the termination resistors on your CANopen or PROFIBUS network before assuming the processor is dead. If the hardware has suffered a fatal failure, contact our engineering team immediately with your part number for an urgent replacement.

Frequently Asked Questions (FAQs)

Q: Can you supply obsolete Kuhnke relays that were discontinued after 2004?
A: Yes! Sourcing discontinued and legacy Kuhnke relays is one of our core specialties. Send us a picture of the old relay and its schematic diagram printed on the side, and we will source the exact match or the certified direct drop-in replacement.

Q: What is the relationship between Kuhnke and Hengstler?
A: Kuhnke acts as an official distribution and integration partner for Hengstler. This allows us to supply you with both Kuhnke’s control systems and Hengstler’s precision encoders as a complete, guaranteed-compatible package.

Q: Do you ship replacement solenoids and valves internationally?
A: Absolutely. Atlantech Drives offers fast, secure, worldwide shipping on all Kuhnke pneumatics and electronics, ensuring your facility experiences minimal downtime.
